Very frosty morning - black ice

It looked very dangerous this morning at the junction of Waverly Road and Cawdor Road. Black ice was covering the roads and the pavements. The Gurnmeister was getting the early train and even the platforms were a sheet of ice. Was it just a localised problem or were other areas of the town hit? Did Highland Council get around to doing anything about it or does gritting only start after 06.00 a.m. ? How was it in your part of town?
